In each Chauvisi (set of 24 Tirthankars) there are exactly 24 Tirthankars. Their names in our present time‑cycle (Bharat Kshetra, current Avasarpini) are:

1. Rishabhanath (Adinath)
2. Ajitnath
3. Sambhavnath
4. Abhinandan­nath
5. Sumatinath
6. Padmaprabhu
7. Suparshvanath
8. Chandraprabhu
9. Suvidhinath (Pushpadant)
10. Shitalnath
11. Shreyansnath
12. Vasupujya
13. Vimalnath
14. Anantnath
15. Dharmanath
16. Shantinath
17. Kunthunath
18. Aranath
19. Mallinath
20. Munisuvratnath
21. Naminath
22. Neminath (Arishtanemi)
23. Parshvanath
24. Mahavir (Vardhaman Swami)

Both Digambar and Shvetambar accept these 24 names and this order. They differ only in a few details (for example, Mallinath’s gender, some parental names), not in the number or sequence.
